Here in Norway most people can get guns, we have a few rules though. You basically just need a license, so everyone that needs it can get it.
If someone is considered unfit to own a weapon, they will never own a weapon, even if they had previously owned a license.
That is it for the rules basically, I personally don't own one, mostly because there is no need to own any. I may get one later if I want to start hunting though.
But hunting is quite expencive, so I won't get one in the near future.
